Abstract: 

This paper reports the design, simulation and characterization of two filtenna structures for Ku-band application. This also presents a comparative study of inductive and capacitive loaded Split Ring Resonator (SRR) in filtenna design. The proposed filtenna structures have the merits of compact size, light weight, low cost and uncomplicated fusion with other planar circuits, in comparison to other circuits. The filtenna structures were simulated with HFSS v.13 software and the results are experimentally verified. The proposed filtenna structures are measured at IIT, Roorkee using FieldFox Microwave Analyzer (N9918A) and anechoic chamber. A good agreement between the simulated and the measured result validates the design. The achieved bandwidth and peak gain of the filtenna structure-I is 3300 MHz and 4.87 dBi respectively for Ku-band. Similarly, the filtenna structure-II resonates at Ku-band with bandwidth 1800 MHz and the peak gain is about 4.8 dBi. The fractional bandwidth possessed by filtenna structure-I and II are 20.62% and 12.77% respectively at resonance. The total build up area of the both proposed structure is about 909.09 mm2, which is most advantageous feature for ku-band application. It also exhibits low insertion loss and low harmonics at higher frequencies.
